Exhaust Smoke

[MarkoBarthel]

In Ship Setup, add Bridge Equipment, then select the type Exhaust. Choose Engine1, Engine2 or Generator and set its position, rotation and output values.

The editor's generator selector starts at 1 for convenience. JSON and the Blueprint Generator Index start at 0.

The editor shows an outlet placement marker, not a live smoke preview. Save JSON and reload the ship to apply your changes. Creator-locked protected ships cannot have their settings edited; configure the original FBX-based version and export a new release.

 

Merge these entries into the existing `bridgeEquipment` array. Keep other entries; do not create a second array with the same key. Every entry needs a unique `id`.

 

```json code
{
  "bridgeEquipment": [
    {
      "id": "main_engine_exhaust",
      "type": "Exhaust",
      "action": "Engine1",
      "positionCm": [-500, -100, 800],
      "rotationDeg": [0, 0, 0],
      "exhaustEnabled": true,
      "exhaustAutoRPM": true,
      "exhaustIdleRate": 12,
      "exhaustFullRate": 70,
      "exhaustIdleSpeed": 40,
      "exhaustFullSpeed": 120,
      "exhaustScale": 1
    },
    {
      "id": "second_engine_exhaust",
      "type": "Exhaust",
      "action": "Engine2",
      "positionCm": [-500, 100, 800],
      "rotationDeg": [0, 0, 0],
      "exhaustIdleRate": 12,
      "exhaustFullRate": 70,
      "exhaustScale": 1
    },
    {
      "id": "generator_1_exhaust",
      "type": "Exhaust",
      "action": "Generator",
      "generatorIndex": 0,
      "positionCm": [-700, 0, 900],
      "rotationDeg": [0, 0, 0],
      "exhaustAutoRPM": true,
      "exhaustIdleRate": 3,
      "exhaustFullRate": 15,
      "exhaustIdleSpeed": 20,
      "exhaustFullSpeed": 60,
      "exhaustScale": 0.6
    }
  ]
}

 

Positions are ship-local centimetres: +X forward, +Y starboard, +Z up. Rotation order is `[pitch, yaw, roll]`, in degrees. Position values above are examples, not automatic funnel detection.

| Field | Default | Meaning / range |
| --- | --- | --- |
| `action` | `Engine1` | `Engine1`, `Engine2` or `Generator` |
| `generatorIndex` | `0` | Generator index, 0–63 |
| `exhaustEnabled` | `true` | Enables this outlet |
| `exhaustAutoRPM` | `true` | Uses the assigned machine's RPM range |
| `exhaustIdleRPM` | `700` | Manual lower RPM, 0–100000 |
| `exhaustFullRPM` | `4200` | Manual upper RPM, 1–100000; must exceed the lower value |
| `exhaustIdleRate` | `12` | Lower output, 0–2000 particles/second |
| `exhaustFullRate` | `70` | Upper output, 0–2000 particles/second |
| `exhaustIdleSpeed` | `40` | Lower exit speed, 0–10000 cm/s |
| `exhaustFullSpeed` | `120` | Upper exit speed, 0–10000 cm/s |
| `exhaustScale` | `1` | Smoke sprite size multiplier, 0.01–100 |

 

Currently the shared `bridgeEquipment` limit of 64 entries includes exhaust outlets, instruments, lights, antennas and controls.
